Abstract: The present invention relates to a leak detection system for checking the leak-tightness of an object, the system including: a device for pressurising a space; a first pressure sensor configured to measure the variations in pressure of the pressurised space; a second pressure sensor configured to measure the variations in ambient pressure, such as atmospheric pressure; an electronic entity configured to determine a leak depending on the variations in the pressure ?P in the pressurised space and the variations in the ambient pressure ?Pext, the variations ?P, ?Pext being measured over a predetermined test time interval ttest by the first and second sensors, respectively.

Abstract: The present invention relates to a device (1) for detecting leaks for a motor vehicle battery pack, said device (1) comprising:—a pneumatic circuit (100) comprising a plurality of valves (V1, V2, V3) and a pressure sensor (106);—at least one connector (7) allowing to connect said pneumatic circuit (100) to at least one element of the battery pack; said device (1) being configured to carry out at least one procedure for detecting leaks on at least one element of the battery pack via said pneumatic circuit (100) and said connector (7).
